This paper describes the different catalytic surfaces of Pd/Sn formed before electroless copper deposition onto a glass substrate. In this study, silanization of the glass surfaces with ͑3-aminopropyl͒ trimethoxysilane was used to provide a surface-coupled layer of functional molecules to assist in the adsorption of Pd/Sn catalyst and the subsequent copper deposition. The composition and microstructure of the modified glass surfaces were characterized by X-ray photoelectron spectroscopy ͑XPS͒ and time-of-flight secondary ion mass spectrometry. These showed that catalytic Pd/Sn structures on the surface changed with increasing immersion time in the catalyst bath. The core-level XPS spectrum of Pd indicated that metallic Pd͑0͒ became more significant in the catalyst layer than Pd͑II͒ with the increasing immersion time. A model of the adsorption process is proposed to explain these changes. It was observed that too high a quantity of Pd͑0͒ does not always improve the adhesion of the Cu deposits in the electroless process.

Uniform and well-crystallized NaLa(MoO 4 ) 2 microspheres were prepared by a facile one-step hydrothermal synthesis without involving any surfactants or templates. The as-obtained products were systematically characterized by powder X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), photoluminescence (PL), and photoluminescent excitation spectra (PLE). The influence of the starting pH value on the phase and morphology of NaLa(MoO 4 ) 2 microspheres was discussed. Furthermore, the formation mechanism of the microspheres was dominated by the consequence of a fast crystallization, dissolution and recrystallization. Finally, the luminescent properties of Eu 3+ and Dy 3+ ion activated NaLa(MoO 4 ) 2 microspheres were investigated. The results demonstrated that NaLa(MoO 4 ) 2 :Ln 3+ (Ln = Eu, Dy) microspheres exhibited good luminescent properties and might have potential applications in lighting technology.

were found to determine the size and morphology of the as-prepared microstructured YF 3 . The prepared samples were systematically characterized by powder X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), photoluminescence (PL) and photoluminescent excitation spectra (PLE). Detailed proofs indicated that the process of growing different morphologies of YF 3 :Eu 3+ microparticles were dominated by different growth mechanisms. Furthermore, photoluminescent properties were also investigated.
